as already said bikes will always be faster than a car due to the weight, bit different on track as they have less grip in the corners but make up for it on the straight

clarkson done a test like that once with a r1 ridden by a british superbike champ against a porche 911 carrera 4 driven by jason plato, the car won round the track
